Technical Field

[0001] This invention relates to the field of agricultural equipment, specifically to a crop growth data acquisition device. Background Technology

[0002] In the research and development stage of some new crops, it is usually necessary to grow a small number of actual crop plants in the laboratory or experimental greenhouse for observation. In order to speed up the research progress, very good growing conditions are usually provided so that the plants can grow and develop rapidly. This requires data collection from the plants to be carried out every day in order to collect enough data under the rapid growth of the plants.

[0003] In data collection, data on plant height, the relationship between plant height and root size, and the relationship between plant height and water and fertilizer consumption are all very important and necessary. However, collecting data on plant height, root system, and water consumption is very cumbersome, usually requiring multiple methods including measuring with a tape measure, soil collection, and even digging up the soil. The operation is complicated and the collection is difficult. Therefore, a new device is needed to collect this data in the preliminary stage to save research time. Summary of the Invention

A transverse moving component is located on one side of the base plate where the connecting rods are located. A longitudinal moving component is located on the transverse moving component. A photoresistor element is located on the longitudinal moving component. A touch switch is located at the bottom of the photoresistor element. When the touch switch moves directly above any set of detection components, it can activate the detection components to extend into the soil for detection.

The connecting frame is fixed to the light source. The rotating cover is rotatably connected inside the connecting frame. The bottom of the rotating cover is connected to the output shaft of the rotating motor. The rotating motor is fixed to the bottom of the connecting frame.

[0007] Preferably, the rotating cover has light-transmitting holes on its side wall.

[0008] Preferably, the lateral movement component and the translation component are connected to the same switch and can be controlled by the switch to move synchronously.

[0015] 2. The detection component in this invention can be linked with the touch switch when measuring the height of the plant. At the same time as measuring the height, it can measure the soil moisture content at different distances from the plant roots.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8This invention provides a technical solution: a crop growth data acquisition device, comprising a base plate 1, a connecting rod 2, a vertical rod 3, and a light source assembly 4. The base plate 1 is evenly distributed with several sets of detection components 5. The side of the base plate 1 is connected to the bottom of the vertical rod 3 via the connecting rod 2. The top of the vertical rod 3 is equipped with the light source assembly 4, which emits stable light. A transverse movement assembly 6 is located on one side of the base plate 1 where the connecting rod 2 is located. A longitudinal movement assembly 7 is located on the transverse movement assembly 6. A photoresistor element 8 is located on the longitudinal movement assembly 7. A touch switch 9 is located at the bottom of the photoresistor element 8. The touch switch 9 moves to... When any set of detection components 5 is directly above, the detection component 5 can be activated to extend into the soil for detection. The light source emitted by the light source component 4 illuminates the shadow formed on the base plate 1 on the crop plant. Combined with the maximum height of the shadow measured by the photoresistor element 8, and given the known data such as the height of the light source, the distance of the light source should be at the farthest end, and the maximum height of the shadow, the height of the plant can be measured according to the principle of similar triangles. With daily data recording, the growth status of the crop can be known. The transverse component 6 and the longitudinal component 7 used are motor lead screw guides that drive the lead screw and move the moving block on the screw through the lead screw.

[0035] In this embodiment, the light source assembly 4 includes a translation assembly 41, a light source 42, a connecting frame 43, a rotating cover 44, and a rotating motor 45. The translation assembly 41 is fixed to the side of the vertical rod 3 via a base plate 46. The light source 42 is fixed on a slide on the translation assembly 41 and can be moved by the slide. The connecting frame 43 is fixed to the light source 42. The rotating cover 44 is rotatably connected inside the connecting frame 43. The bottom of the rotating cover 44 is connected to the output shaft of the rotating motor 45. The rotating motor 45 is fixed to the bottom of the connecting frame 43. The translation assembly 41 can drive the light source 42 to move back and forth on the track. When moving, the light emitted by the light source 42 can illuminate the crop plants between the vertical rod 3 and the base plate 1, and form a light and shadow on the base plate 1 for measurement. The translation assembly 41 used is a motor lead screw guide rail that moves by a motor driving a lead screw and then by the lead screw driving a moving block on the screw.

[0036] In this embodiment, the side wall of the rotating cover 44 is provided with a light-transmitting hole 441. The light-transmitting hole 441 is rectangular in shape, so that the emitted light is approximately parallel light, which can improve the measurement accuracy. Several sets of light-transmitting holes 441 can be set as needed. During measurement, the rotation of the rotating motor 45 allows light to pass through different light-transmitting holes to generate multiple sets of data, form a comparison, and eliminate errors.

[0037] In this embodiment, the transverse component 6 and the translation component 41 are connected to the same switch and can be controlled by the switch to move synchronously. In this way, when the light source 42 is driven to move to measure multiple crops, the photoresistor element 8 on the transverse component 6 can be kept in sync with the light source 42, thereby avoiding data errors.

[0038] In this embodiment, the detection component 5 includes an inductive switch 51, an electric actuator 52, and a soil moisture sensor 53. The inductive switch 51 is fixed inside the housing and located on the upper surface of the base plate 1. The housing is installed inside the base plate 1. The electric actuator 52 is fixed inside the housing. The soil moisture sensor 53 is installed on the output shaft of the electric actuator 52. The inductive switch 51 is electrically connected to the electric actuator 52. When the inductive switch 51 is aligned with the trigger switch 9, it will activate the electric actuator 52 to insert the soil moisture sensor 53 into the soil. The photoresistor element 8 is longitudinally moved... When the track 7 moves, the trigger switch 9 will activate the electric actuator 52 at each induction switch 51 as it passes directly above it, allowing the soil moisture sensor 53 to extend into the soil and measure the water content in the soil. This allows for observation of whether plant roots are spreading in the area. The soil moisture sensor 53 can be a soil moisture sensor that measures water content, or a nitrogen, phosphorus, and potassium sensor that measures soil fertility as needed. By judging the changes in the data collected each time the water and fertilizer are uniformly applied to the soil, the growth range of the plant roots can be observed from the side.

[0039] In this embodiment, a photoresistor block 82 is installed on the top of the slide within the longitudinal movement assembly 7. When the light from the light source 42 shines on the plant and forms a shadow on the base plate 1, the photoresistor block 82 is moved by the longitudinal movement assembly 7 from the end closest to the plant to the end furthest from the plant. After the shadow is cast, the resistance of the photoresistor block 82 changes. By measuring the change in resistance value as it moves a certain distance on the longitudinal movement assembly 7, the length of the shadow can be obtained, thereby completing the measurement of the plant height.

[0040] In this embodiment, the touch switch 9 is fixed on the lower surface of the slide in the longitudinal movement assembly 7. While measuring the plant height, it also measures the moisture or fertility in the soil. By combining the plant height data with the data on the changes in moisture and fertility at different points away from the plant roots, the relationship between plant height and the data on the consumption of moisture and fertility can be obtained.

[0041] In this embodiment, the base plate 1 is also provided with a support seat 10, and the two ends of the longitudinal moving component 7 are respectively located on the transverse moving component 6 and the support seat 10, so as to complete the balanced support of the longitudinal moving component 7.

[0042] Please see Figure 9In the diagram, 'a' represents the height of the light source 42 above the ground, which is a known value; 'b1' is the projection of the distance between the plant root and the light source 42 onto the ground, which can be obtained through measurement and is also a known value; 'b2' is the distance between the plant root and the photoresistor block 82, which can be obtained by measuring the resistance change of the photoresistor block 82 as it moves on the longitudinal moving component 7. Therefore, based on the principle of similar triangles, the plant height 'x' is calculated as follows:

[0043] x = a*b2 / b1+b2.

[0044] Working principle: Crops are planted between the vertical rod 3 and the base plate 1. After planting, when data collection of crop plants is required, the translation component 41 drives the light source 42 to move back and forth on the track. During movement, the light emitted by the light source 42 illuminates the crop plants between the vertical rod 3 and the base plate 1, forming a light and shadow on the base plate 1. The photoresistor block 82 is moved from the side of the longitudinal translation component 7 closest to the plant to the side farther away from the plant. After the shadow is cast, the resistance of the photoresistor block 82 changes. By measuring the change in resistance value when the sliding block 81 moves to a certain distance, the length of the shadow can be obtained. Given the height of the light source and the distance of the light source at the farthest end, Given data such as the maximum height of the shadow and the light source, the height of the plant can be measured based on the principle of similar triangles. By recording data daily, the growth status of the crop can be determined. At the same time, the sliding block 81 will drive the touch switch 9 to move. When the touch switch 9 passes directly above each sensor switch 51, it will activate the electric push rod 52 at that location, allowing the soil moisture sensor 53 to extend into the soil and measure the water content in the soil. This allows for observation of whether the plant's roots have spread in that location. The measurement of plant height is completed simultaneously with the measurement of soil moisture or fertility. By combining the plant height data with the data on changes in moisture and fertility at different points away from the plant roots, the relationship between plant height and the data on water and fertility consumed can be obtained.

[0045] Based on the above, this invention can measure the height of crop plants by means of the cooperation between the light source component and the photoresistor element, replacing the original method of measurement by manual tape measure or string, thus improving measurement efficiency and saving measurement time.

[0046] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
